Abstract

Disclosed herein is a printed circuit board. In the printed circuit board provided with a router machining line to be partitioned into a unit region in which a plurality of unit substrates are formed and a dummy region enclosing the unit region, the unit region and the dummy region are formed in a plurality of layers and the printed circuit board includes detection coupons formed on each of the plurality of layers.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A printed circuit board provided with a router machining line to be partitioned into a unit region in which a plurality of unit substrates are formed and a dummy region enclosing the unit region, the unit region and the dummy region being formed in a plurality of layers, the printed circuit board comprising:
 detection coupons formed on each of the plurality of layers.   
     
     
         2 . The printed circuit board according to  claim 1 , wherein the detection coupon has a plane shape formed in a ‘V’-letter shape. 
     
     
         3 . The printed circuit board according to  claim 2 , wherein the detection coupon is formed on the router machining line to extend over the unit region and the dummy region. 
     
     
         4 . The printed circuit board according to  claim 2 , wherein widths of sections of each of the detection coupons exposed on a section of the router machining line are detected to detect eccentricity. 
     
     
         5 . The printed circuit board according to  claim 2 , wherein an interval between the detection coupons for each layer exposed on the section of the router machining line widths is detected to detect eccentricity. 
     
     
         6 . A printed circuit board provided with a router machining line to be partitioned into a unit region in which a plurality of unit substrates are formed and a dummy region enclosing the unit region, the unit region and the dummy region being formed in a plurality of layers, the printed circuit board comprising:
 detection coupons formed on each of the plurality of layers; and   a plurality of graduated coupons formed on sides of the detection coupons at a predetermined interval.   
     
     
         7 . The printed circuit board according to  claim 6 , wherein the detection coupon has a plane shape formed in a ‘V’-letter shape. 
     
     
         8 . The printed circuit board according to  claim 6 , wherein the graduated coupon is formed to be parallel with the other side of the detection coupon.
